Abstract

A styrene-degrading bacterium isolated from soil showed the capability to respire styrene, styrene oxide, phenyl acetaldehyde, phenyl acetate, phenol, catechol, succinate, pyruvate, acetate and acetaldehyde. Succinate-grown ceils respire styrene. The strain was used to inoculate a biofilter with lava stones as carrier material. After a short adaptation period the biofifter was able to remove over 98% of the incoming styrene (I mmol.m−3) at a space velocity of 160 h−1.
